HOW TO LIMIT WHAT SYNCS TO OUTLOOK 2016 FOR MAC UPDATE
The May 3, 2016, update for Outlook 2016 allows you to set these additional values by using the SyncWindowSettingDays registry data. The Outlook 2016 user interface lets you set the Mail to keep offline setting to the additional values of 3 days, 1 week, and 2 weeks. Older items in shared mailboxes and public folder favorites that are stored on the server are not returned in the search results.

Also, when you search in shared mailboxes and public folder favorites that are affected by the Mail to keep offline setting, only items that are cached on your local computer are returned in the search results. Unlike the folders your own mailbox, shared mailboxes and public folder favorites that are affected by the Mail to keep offline setting do not provide a link to view more items from the server that is running Exchange Server.
